BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a winding machine, and more particularly to an unloading mechanism of a winding machine.

2. The Related Art

Conventionally, an automatic winding machine provides an unloading mechanism to effectually solve the problem that it is hard to unload bobbin materials from the automatic winding machine. But the automatic winding machine is easy to damage the bobbin materials in process of unloading.

Please refer to FIG. 1 and FIG. 2. The unloading mechanism of the automatic winding machine includes a basic tray 300 engaged with a main axis and four unloading units. Each unloading unit includes a sliding pillar 500 disposed in the front of the basic tray 300. A pushing block 600 projecting out of the basic tray 300 defines an inclined plane at the front head thereof and drives the end of the sliding pillar 500 moving along the inclined plane. The pushing block 600 fixedly connects with a pushing pillar 700 and a pair of guiding pillars 800 distributing at bilateral sides of the pushing pillar 700. The pushing pillar 700 and the guiding pillars 800 slideably pass through the basic tray 300. The other end of the pushing pillar 700 is fixed on a turntable 400 which is arranged on the main axis and behind the basic tray 300. The space between the two guiding pillars 800 is wider than the space between the inner edge and the outer edge of the turntable 400, so one of the guiding pillars 800 is adjacent to the inner edge of the turntable 400 and the other guiding pillar 800 is adjacent to the outer edge of the turntable 400, ensuring the turntable 400 giving a push force to the pushing pillar 700 exactly. A restoring spring 900 is set around the pushing pillar 700 for making the pushing block 600 restore to the original position after the bobbin materials are unloaded from the automatic winding machine.

As mentioned above, because the pushing block 600, the pushing pillar 700, the guiding pillars 800 and the restoring spring 900 are integrated together, the sizes of them are limited, and the intensions of them are not enough. Therefore, the pushing pillar 700, the guiding pillars 800 and the restoring spring 900 are easy to deform in use.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to provide a winding machine to wind and unload a bobbin material. The winding machine includes a frame. A main axis is fixed on the frame and horizontally extends forward. A winding tray is engaged on a front end of the main axis and defines long slots therethrough. Winding spindles pass through the long slots of the winding tray respectively and stretch forward. And an unloading mechanism includes a basic tray. The basic tray mounted on the main axis between the winding tray and the frame defines through-holes and guiding holes therethrough. Each through-hole is correspondingly adjacent to one of the guiding holes. A sub-tray is mounted on the main axis between the basic tray and the frame. The unloading mechanism further includes unloading units, and each of the unloading units has a panel member which is pivotally connected to the front of the basic tray. The panel member defines an arc track thereon and integrates with a connecting member that is connected to the basic tray by helical springs. The connecting member engages with the winding spindle. A sliding pillar is parallel and slidably located in the front of the basic tray. The sliding pillar projects forward to form a supporting element. The head of the supporting element configures a first idler wheel sustaining an end of the arc track of the panel member. An end of the sliding pillar configures a second idler wheel. A pushing block is moveably received in the through-hole of the basic tray. A front end of the pushing block protrudes out of the through-hole and defines an inclined guide surface thereon to hold the second idler wheel of the sliding pillar, and a back end of the pushing block extends to be fixed on the sub-tray. A guide pillar is moveably received in the guiding hole, and one end of the guide pillar is fixed on the sub-tray. A reinstating spring encircles the guide pillar. One end of the reinstating spring is against the basic tray, and the other end of the reinstating spring is against the sub-tray. And a driven mechanism is configured between the frame and the sub-tray for providing a force to the sub-tray.

As described above, the pushing blocks and the reinstating springs are assembled separately, so the sizes of them are not limited, and the intensions of them are increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 3 and FIG. 4, a winding machine with an unloading mechanism of the present invention is used for winding and unloading a bobbin material. The winding machine includes a frame 1, a main axis 2 fixed on the frame 1 and horizontally extending forward, and a winding tray 3 engaging on a front end of the main axis 2 and defining four long slots 31 therethrough. Four winding spindles 4 are received in the long slots 31 of the winding tray 3 respectively and stretch forward, distributing symmetrically in up-down direction and left-right direction. The winding machine further includes an unloading mechanism which includes four unloading units distributed symmetrically in up-down direction and left-right direction correspondingly to the four winding spindles 4 and connecting to the four winding spindles 4 respectively in the preferred embodiment. The unloading mechanism further includes a basic tray 10 between the winding tray 3 and the frame 1, and a sub-tray 50 between the basic tray 10 and the frame 1. Both the basic tray 10 and the sub-tray 50 are mounted on the main axis 2 and parallel with the winding tray 3. A driven mechanism is mounted on the frame 1 and behind the sub-tray 50.

Referring to FIG. 5, the basic tray 10 defines four through-holes 101 and four guiding holes 102 which are adjacent to the corresponding through-holes 101 therethrough. Each unloading unit includes a first receiving element 103 and a second receiving element 104 protruding forward from a front surface of the basic tray 10. The first receiving element 103 receives a pair of pads 1031 in a row in a front surface thereof. Bilateral sides of the first receiving element 103 vertically define a long groove 1032. A receiving hole 1033 is defined in the center of the first receiving element 103 and passes through the first receiving element 103 vertically. The receiving hole 1033 communicates with the grooves 1032.

A sliding pillar 20 which is in circular shape is vertically and slidably received in the receiving hole 1033 of the first receiving element 103 and the second receiving element 104. The sliding pillar 20 projects forward to form a supporting element 201 substantially at center thereof and above the second receiving element 104. The head of the supporting element 201 configures a first idler wheel 202. The lower end of the sliding pillar 20 that stretches out of the second receiving element 104 and extends downward configures a second idler wheel 203.

Two pairs of limit screws 120 are provided to locate a pair of first helical springs 30 between the first receiving element 103 and the second receiving element 104. One pair of the limit screws 120 are respectively inserted in the grooves 1032 and further inserted into bilateral sides of the sliding pillar 20 to locate upper ends of the first helical springs 30 on the bilateral sides of the sliding pillar 20. The other pair of the limit screws 120 are inserted in bilateral sides of the second receiving element 104 to locate lower ends of the first helical springs 30 on the bilateral sides of the second receiving element 104 respectively.

The front surface of the first receiving element 103 defines a projection below the pads 1031 to connect with a panel member 40 which defines an arc track 401 on a back surface thereof. A shaft 5 passes through an upper side of the panel member 40 and the projection of the first receiving element 103 for engaging the panel member 40 with the first receiving element 103 pivotally. A front surface of the panel member 40 couples with a connecting member 100 which is a long bar. A retaining member 110 is mounted on a front surface of the connecting member 100. The winding spindle 4 passes through the long slot 31 of the winding tray 3 and is fixed on the retaining member 110.

A pair of second helical springs 90 are employed for linking the connecting member 100 to the second receiving element 104. Two locating positions that the second helical springs 90 are located on bilateral sides of the connecting member 100 are on the same surface level as the limit screws 120 inserted in the bilateral sides of the second receiving element 104. Hence, one end of the second helical spring 90 is located on the lateral side of the connecting member 100 and the other end of the second helical spring 90 is located on the limit screw 120 inserted in the lateral side of the second receiving element 104. The pads 1031 of the first receiving element 103 sustain a top of the connecting member 100. The first idler wheel 202 of the sliding pillar 20 sustains a lower end of the arc track 401 and further pushes the connecting member 100 forward. Therefore, the second helical springs 90 are in elastic elongation state.

A pushing block 60 is movably received in the through-hole 101 of the basic tray 10. One end of the pushing block 60 defines an inclined guide surface 601. The inclined guide surface 601 protrudes out of the through-hole 101 and holds the second idler wheel 203 of the sliding pillar 20. The other end of the pushing block 60 extends backward and is fixed on the sub-tray 50.

A guide pillar 80 which is used for reducing the side force acting on the pushing block 60 is movably accommodated in the guiding hole 102 of the basic tray 10. An end of the guide pillar 80 couples with a screw cap 801 before the front surface of the basic tray 10 and the other end is fixed on the sub-tray 50. A reinstating spring 70 encircles the guide pillar 80 and is against a back surface of the basic tray 10 and a front surface of the sub-tray 50.

Referring to FIG. 3 and FIG. 4 again, the driven mechanism includes two cylinders 130 which are configured on the frame 1 and distributed symmetrically around the main axis 2. An impelling arm 132 is set on a piston of the cylinder 130. The front surfaces of the impelling arms 132 dispose an impelling tray 131 locating around the main axis 2 and behind the sub-tray 50.

Referring to FIG. 3 and FIG. 6, when the winding machine is in use, firstly operate a switch of the cylinders 130 to drive the impelling tray 131 to move forward and touch a back surface of the sub-tray 50. Then the impelling tray 131 moves forward continually and pushes the sub-tray 50 move forward. Then the reinstating spring 70 is compressed. The moving sub-tray 50 drives the pushing block 60 to move forward to push the second idler wheel 203 of the sliding pillar 20 to roll up along the inclined guide surface 601. Then the sliding pillar 20 is heaved. Therefore, the first idler wheel 202 of the sliding pillar 20 which sustains the lower end of the arc track 401 slides in the concave arc track 401 of the panel member 40. The elastic force storing in the second helical springs 90 are released, causing the connecting member 100 incline to back, and further causing the winding spindle 4 incline. Therefore, the bobbin material is easy to unload from the winding spindles 4 of the winding machine. And at the same time, the first helical springs 30 located between the first receiving element 103 and the second receiving element 104 are elongated. After unloading the bobbin material from the winding machine, operate the switch of the cylinders 130. The compressed reinstating spring 70 drives the sub-tray 50 and the pushing block 60 to restore to the original positions respectively. The elongated first helical springs 30 draw the sliding pillar 20 downward until the first idler wheel 202 of the sliding pillar 20 sustains the lower end of the arc track 401 and further makes the connecting member 100 restore a balance state. Then, the winding spindles 4 restore a horizontal balance state.

As described above, the pushing blocks 60 and the reinstating springs 70 are assembled separately, so the sizes of them are not limited, and the intensions of them are increased.
